He’s been signed to be an attacking, speedy wing back. Playing him at full back is clearly not a like for like comparison. Given that you argue wing backs to be midfielders it’s not hard to see the point
What? He can play both. He’s played four times as many games ar RB over his career than WB. Last season he played 12 at WB and 20+ at RB.
I couldn’t care less if he’s been signed to be an art deco paperweight, he blatantly able to play FB.
